Benefits of technology

[0013]In the infinitely variable speed converter disclosed in PATENT LITERATURE 2 including the multiple dynamo/motors, which are arranged to rotate reversely to each other, and the traction roller inserted therebetween, a flywheel effect due to its large diameter makes rapid change in the revolving speed difficult, but quick speed conversion by the infinitely variable speed converter can solve the problem. Such a rapid change in the revolving speed of the dynamo/motor would also consume enormous current in a non-energy-saving manner, but the infinitely variable speed converter can rapidly change the revolving speed of the drive shaft with no change in the revolving speed of the dynamo/motor to practice energy conservation. However, since the arrangement requires at least two dynamo/motors and the infinitely variable speed converter composed of the traction roller is in a portion in contact with the exterior of the dynamo/motors, each occupying an independent space, it is difficult to thin and compactify the dynamo/motors in the direction of the central shaft. It is hence an object of the present invention to review such a conventional arrangement including at least two dynamo/motors and a speed converter and thereby to provide a new arrangement in which the entire dynamo/motor including a speed converter is thinned and compactified in the direction of the central shaft.
[0014]For a stator formed by annularly disposing permanent magnets or electromagnets, a space is provided in a portion surrounded by at least one rotor arranged to rotate clockwise with at least one of a drive disk and a drive gear, at least one rotor arranged to rotate counterclo

Abstract

An infinitely variable speed converter having at least two dynamo/motors, to reduce the thickness in the direction of the central shaft. A space is provided in a portion surrounded by a rotor arranged to rotate clockwise with either a drive disk or a drive gear, a rotor arranged to rotate counterclockwise with either a drive disk or a drive gear, and a radial interior of a stator formed by annularly disposing field magnets. When a traction roller or a traction gear penetrated by a drive shaft is inserted into the provided space, contacting the drive disk to be subject to a couple and thereby rotating while the traction gear comes into contact with the drive gear, whereby an output can be provided to the drive shaft that penetrates the traction roller or the traction gear, so that the entire structure can be compactified.
